Note that some short <br />circuiting at the Outfall 5A (Pond D) flume was observed. Some water appeared to be slowly migrating under the flume. It <br />was unclear if it was sufficient to make its way through a downstream culvert to Foidel creek. Never the less, one set of water <br />quality samples were collected for analyses and are presented here. A bentonite seal was subsequently utilized to eliminate <br />the short circuiting. The flume will be inspected in the spring, and further repairs made as necessary. Outfall 005A exhibited <br />low flow during the first week of the period, allowing only one sample set to be collected. No exceedances were noted. <br />In order to reduce the amount of paper work, the following certification will be substituted for the actual DMR forms to cover <br />the outfalls, which did not discharge during the period. These outfalls include ponds C (Outfall 004A), E (Outfall 006A), F <br />(Outfalls 007A/MON 7/007XY - all same site), and G (Outfall 008A). <br />CERTIFICATION <br />1 certify under penalty of law that I have personally examined and am familiar with the information submitted herein; and <br />based on my inquiry of those individuals responsible for obtaining the information, I believe the submitted information is <br />true, accurate, and complete. I am aware that there are significant penalties for submitting false information, including the <br />possibility of fine and imprisonment. See 18 U.S.C. § 1001 and 33 U.S.C. § 1319. (Penalties under these statutes may <br />include fines up to $10,000 and/or maximum imprisonment of between 6 months and 5 years.) <br />4 /Z 23 q <br />Brian A.
